So I went and washed the car yesterday, had to move it into the street to dry it (shade in strett) so I put on the flashers and parking lights for no more than an hour. Went to start it and it wouldent turn, barly heard the starter. Called AAA cuz It was easier than getting my dads car int othe street for a jump and it took 2 tries until it started. Drove the car a half mile and left it on for 10 mins wiht lights and AC on per some instructions i read somewhere. Also I usualy keep 2 bluetooth gps's powered into the car and the hella tpms daws a small current along with my bluetooth headset charger. Been doing this for a LONG time and no issues (tpms install was recent-2weeks or so) So this morning the car turned over weak. Ok so I went and unplugged all the gps's and the bluetooth. Left the car today for around 11 hours. Came back and weak started again. So I'm going out tonight and I have jumper cables but I wanna know whats up. The OBC gives me 13.~~ reading while the car is on so I think the alternator is ok?? When I get to my friends house I'll use her dads multimeter to test the voltage by putting the + on the jumper terminal and the - on the gound and report the #...Any ideas? THANKS!
